ROOFING SHINGLE.

Application filed June 29,

The invention relates to roofing shingles, and has for its object toprovide a device of this character having a substantially rectendingoutwardly fromthe under side thereof and having one of its sides inalinement with the side of the body, and an inwardly extending slit orslot in 'the alined side of the projection whereby when the shingles areplaced in 'interengaged and interlocked relation the shingles, whenabutted in courses, will assume their proper po- 'sitions in relation tothe roof as a whole and the projections may be easily and quickly lockedin position, with the inclined sides of the projections of adjacentcourses of shingles.

A further object is to provide a shingle structure of the interlockingtype, which may be easily and quickly interlocked and when interlockedthe sides of the shingles will assume their proper abutting engagementwith shingles of the same course, thereby allowing the laying of a roofwithout the tedious necessity of accurately gaging the position ofshingles, consequently providing a shingle which does not require anexpert or a skilled worker to lay, and materially redifices the timerequired for shingling a mo A further object is to providea shinglehaving a body substantially rectangular shaped and having a projectionV-shaped extending outwardly from one side of the body with its side inalinement with the side of the body, thereby allowing the formation andcutting of shingles from a single piece of material without loss ofmaterial.

With the above and other ob'ects in view the invention resides in thecom ination and arrangement of parts as hereinafter set forth, shown inthe drawing, described and claimed, it being understood that changes inthe precise embodiment of the invention may he made within the scope ofwhat is claimed without departing from the spirit of the invention,

in the drawin Figure l is a pin view out one of the shin- & Figure 52 isa plan view or a section oi a root, formed from the shingies.

Referring the drawing, the numeral 1 signates the rectanguiar shapedbody of e shingle and 5 a substantiaiiy ti-shaped from the outwardly1927. Serial No. 202,425.

under or lower side of the shingle. projection 2 has its side 3 inalinement with the side 4 of the shingle and is provided with aninwardly extending slit or'slot 5 extending inwardly from the side 3thereof. The depth of the slot 5 is of a depth whereby when the shinglesare interlocked as shown in Figure 2 in overlapped courses and thecorners 6 of the recessed sides are in the bottom of the slits or slots5, the sides 4 of the shingle bodies 1 will be in abutting engagementwith the sides 7 of the bodies 1, as clearly shown in Figure 2,therefore it will be seen that the relation of the slots 5 is such thatwhen the corners are interlocked, which can be easily done,'the shingleswhen placed in abutting engagement, during the laying of successivecourses,'will assume their natural positions, consequently the shinglesmay be easily and quickly laid forforming a roof or siding with amaximum amount of speed, and without the use of skilled labor ifdesired.

In laying the roof the lower course a is preferably placed on the roofwith the shingles in abutting engagement and after which, in laying thenext course, it is only necessary for the operator to force the ends ofthe projections of the next course under the projections of the lowercourse a and pull upwardly on the shingles until the corners 6 are inthe bottoms of the slots 5, and at which time the sides 7 and 4 of theshingles will be in position for abutting each other. The laying ofother courses continues in the same manner, and it will be noted, it

-will not be necessary for the operator to measure or use extraordinaryskill in the laying of the shingles of each course, as they willnaturally, after the interlocking operation, fall into their naturalpositions. will be noted that slot 5 is referred to as a slot or slit,and theterm is used, as it is obviousa slit or slot ma he used.

From the above it will e seen that a rooting shingle is provided whichis shaped in a manner whereby shingles may "he formed from a singlepiece of material without the loss of any of the material, whereh wastein course. of manufacture is obviate it will also be seen that apositively interlocking roofing is provided in which the interlockedprojections will be positively prevented from curling, a single siitused in interlocking the projections, thereby obviating excessivebending and as the projections do not have The llO

to interlock with both sides of adjacent projections or shin les, it isobvious that the interlocking may e easily and quickly accomplished withthe minimum amount of time and labor.

The invention having been set forth what is claimed as new and usefulis 1. A roofing shingle comprising a substantially rectangular shapedbody, a projection extending outwardly from one side of the under sideof the shingle, the side of said projection being in alinement with theside of the shingle body, said projection in its alined side beingprovided with an inwardly extending slit.

2. A roofing shingle comprising a substantially rectangular shaped body,a projection extending outwardly from one of the edges thereof, saidprojection having one of its sides in alinement with the side of thebody and a slot extending inwardly into the projection from the alinedside thereof.

3. A roofing shingle comprising a substantially rectangular shaped body,an outwardly tapered projection carried by said body, one side of saidprojection being in alinement with one side of the body and a slitextending into the projection from the alined side thereof.

4. A roof formed from a plurality of overlapped courses of shingles, theshingles of each course comprising alined abutting rectangular shapedbodies, V-shaped projections extending outwardly from the lower edges ofthe bodies at one side thereof, sides of said projections being inalinement with abutting ends of the shingle bodies, said projectionshaving inwardly extending slots in their alined sides, the bottoms ofsaid slots being positioned whereby the projections of superimposedcourses, when interlocked with the projections of lower courses, willlimit the positions of the bodies of the courses to abutting alinedrelation.

In testimony whereof I afiix my signature.
